QEMU is gaining introspectable statistics which can be queried via the "query-stats" QMP command. This patchset aims to add an API for the same. The returned JSON for "query-stats" is an array of objects containing their own respective array of statistics. Patch 1 adds the API which returns the deserialized JSON in the form of a GPtrArray of GHashTables. Patch 2 adds the "query-stats" to QEMU capabilities. Patch 3 uses the API to query the halt poll success time and the halt poll failure time. Relevant QEMU patches can be found here: https://lore.kernel.org/all/20220523150509.349412-1-pbonzini@xxxxxxxxxx/ This patchset is part of the 2022 GSOC contributor project. All reviews and comments are appreciated :).
